Climate is generally defined as average weather, and as such, climate change and weather are intertwined. Observations can show that there have been changes in weather, and it is the statistics of changes in weather over time that identify climate change. While weather and climate are closely related, there are important differences.
A common confusion between weather and climate arises when scientists are asked how they can predict climate 50 years from now when they cannot predict the weather a few weeks from now. The chaotic nature of weather makes it unpredictable beyond a few days. Projecting changes in climate (i.e., long-term average weather) due to changes in atmospheric composition or other factors is a very different and much more manageable issue. As an analogy, while it is impossible to predict the age at which any particular man will die, we can say with high confidence that the average age of death for men in industrialised countries is about 75.
Another common confusion of these issues is thinking that a cold winter or a cooling spot on the globe is evidence against global warming. There are always extremes of hot and cold, although their frequency and intensity change as climate changes. But when weather is averaged over space and time, the fact that the globe is warming emerges clearly from the data.

Climate is defined as the average weather, and therefore, climate and weather overlap. Studies indicate that changes have occurred in the weather, and in fact, statistics of changes in weather with time determine climate change. Although climate and weather are closely related, significant differences separate them. Climate and weather are often confused when scientists ask about the predictability of a weather for 50 years to come. They can not predict the weather for a few weeks to come, as mixed weather makes it impossible for days to predict. This is different from the expectation of changes in climate (such as long-term weather) from changes in the composition of the atmosphere and from other factors, which is not difficult to control. It is impossible to determine the date of death of any person, but it can be established with confidence that the death rate in industrialized countries is 75 years. One thing that often involves people is the belief that a cold winter or a cold spot on the globe indicates that there is no global warming. There is always a limit to cold and heat, despite the changing power and frequency of climate change. Global warming, however, may begin when the weather is one in different times and places.
Extreme weather does not prove the existence of global warming, but climate change is likely to exaggerate it—by messing with ocean currents, providing extra heat to forming tornadoes, bolstering heat waves, lengthening droughts and causing more precipitation and flooding.
“A changing climate leads to changes in the frequency, intensity, spatial extent, duration and timing of extreme weather and climate events, and can result in unprecedented extreme weather and climate events,” reports the Intergovernmental Panel on Climate Change (IPCC), an independent group of leading climate scientists convened by the United Nations to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts.
What is the Relationship between Climate Change and Weather?
In the climate zones, average temperature patterns, precipitation, etc. are emerged over the seasons. If permanent deviations from these average processes occur, this is called climate change. In the course of geological development, there have been several climate change. For northern and central Europe, can last the time between two climate periods about 100,000 to 125,000 years, see Petit 2009.
Especially in arid climates, significant deviations from the average annual temperature have occurred. The dry times are prolonged, the average amount of precipitation is decreasing. The melting of the glaciers leads to a significant increase in sea levels. For climate change, the CO2 content may not be the only indicator. An increase in extreme weather events is observed worldwide.
Climate change (weather condition for a long period of time) has a clear effect on weather (short-term weather, one or two days). This effect is shown by temperature variability, wind movement, humidity, atmospheric pressure, condensation etc.
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather within the context of longer-term average conditions. Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.[1]
Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy.[1] Most weather phenomena occur in the lowest level of the atmosphere, the troposphere,[2][3] just below the stratosphere. Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time.[4] When used without qualification, "weather" is generally understood to mean the weather of Earth.
Weather is driven by air pressure, temperature and moisture differences between one place and another. These differences can occur due to the sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the Hadley Cell, the Ferrel Cell, the Polar Cell, and the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. On Earth's surface, temperatures usually range ±40 °C (−40 °F to 100 °F) annually. Over thousands of years, changes in Earth's orbit can affect the amount and distribution of solar energy received by the Earth, thus influencing long-term climate and global climate change.
The comment of Dhia Taain contains essential elements of how climate change can be defined or determined. What factors cause climate change and how these factors interact, that a climate change occurs, are still not well identified and controversial for our time. From studies at ice stratification in the antarctic, at the ice inclusions such as air, animal and plant remains is currently a confirmed fact that at a distance of> = 100,000 years, a warm or cold time have to expected. The description as global warming does not do justice to the consequences of climate change, which is characterized not only by an average increase in temperature, but also by water shortage, increasing sea level, average increase in extreme weather conditions, etc.
Climate change to relate alone on increasing of CO2 concentration (ppmv) does not meet the essential requirements. But that's why measures to stop the CO2 concentration from growing are not wrong.
Weather is evidently a short-term state of the atmosphere in a certain place.
The climate, on the other hand, refers to longer periods - at least 30 years. Typical conditions are derived from a large number of weather observations. This allows the climate of a region to be determined. The climate not only represents the average weather conditions, but also describes the probabilities for extreme events and deviations from the mean.
The climate has changed quite a few times in the course of 4.6 billion years of geological history. After very warm phases came long ice ages, which in turn were replaced by warm periods. The change period is approximately 125,000 ( > 100,000) years.
Causes of natural climate changes
- a change in the incident solar radiation, e.g. through changes in the distance between the sun and the earth or the activity of the sun;
- a change in the proportion of the reflected solar radiation, e.g. by a changed reflexivity of the atmosphere or the earth's surface;
- a change in the heat radiation emitted by the earth, e.g. by changing the greenhouse gas concentration.
It is possible to detect (measure) a relationship between deviations (temperature difference) of the temperature from the mean and the CO2 concentration in the atmosphere.
